. MACHINE FOR PRINTING WARP.

Specification of Letters Patent. Application filed February 28, 1906.Serial No- 303.399.

Patented Dec. is, 1906.

To all whom/it may concern.-

Be it known that I, AUGUST 0. SoHoEN, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Machine for Printing Warp, of which thefollowing is a specification. 1

My invention relates to a warp-printing machine; and it consists of adrum on which warp may be wrapped adapted to be reduced in diameter,whereby the warp may be readily removed. To this end the periphery ofthe-drum is formed. of movable parts or sections which may be drawninwardly, provision being also made for restoring the periphery of thedrum to its normal condition and looking it against improper motion, themeans employed being hereinafter described, and the -novel features ofthe same being pointed out in the claims. Y It also consists of detailsof as will be hereinafter described.

Figure 1 represents a perspective view of a warp-printing machineembodying my invention. Fig. 2 represents a partial side elevation andpartial vertical section thereof. Fig. 3 represents a partial side;elevation and partial vertical section of a portion of themachine,certain parts thereof being in different position from thatshown in Fig. 2. Fig.

construction,

4 represents a perspective view of the means employed for removing theprinted warp from the drum. ,Fig. 5 represents an end view thereof. Fig.6 represents a vertical section of a portion on line mm, Fig. 2. Fig. 7represents a side elevation of a portion detached from Fig. 6.

Similar letters of reference indicate corre sponding parts in thefigures.

A designates a drum, and B the driving shaft thereof, the latter havingits bearings on the frame C. On the inner periphery ofthe drum is thecircular rack A, with which meshes the pinion A whose shaft carries thepulley A which receives power from any suitable source, whereby the drummay be rotated.

The periphery of the drum is formed partly of movable sections D E, eachofwhich is pivotally connected, as at F G, with the cross-bars H, whichare secured to the interior of the remaining portion of the periphery,it being noticed thatsaid sections D E are adapted to move inwardly,thus in a measure collapsing the drum, as shown in Fig. 3. Pivotallyconnected with the section D are the racks J, which enter the drum andare engaged by the pinions K, Whose shafts L have their bearings on thecross-bar H.

-On the shaft L is the sprocket-wheel M,

around which passes the sprocket-chain N, which also engages with thesprocket-wheel P, whose shaft Q is mounted on a fixed member within'thedrum A and has connected with it the hand-wheel R for operatingpurposes. I

Pivotally connected with the interior of the section ,E are the links S,which are slotted to receive the studs T on the crossbars H, said linksthus forming guides for said section E in its inward and outwardmotions.

It will be seen that the sections D E have theircontiguous endslap-jointed, as at U, whereby the section E is prevented from droppingbelow the section D in either of their positions, as shown in Figs. 2and 3.

When the drum is in normal condition, as in Fig.2, the warp may be woundaround the same, as shown in Figs. 1 and 5, when the printing may beaccomplished, the mechanism for which being omitted for purposes ofclearness.

After the printing the yarn is to be removed. To this end the shaft Q isrotated, whereby the racks J are drawn inwardly and with them thesection D. As the section E is now no longer supported by said sectionD, the former follows the latter when the parts assume the positionShown in Fig. 3, thus in a measure collapsing the drum or reducing itsdiameter, whereby the yarn is loose on the drum and may be readilyremoved for fur ther treatment. I I

Pivotally connected with a side of the frame-C are the bars V, on theouter ends'of which are the laterally-extending pins V. Latches or hooksV are also pivotally connected with the bars V, the same being adapt-'ed to be engaged with studs V on the side of the frame, so as to retainthe pins in operative position, as shown in Fig. land the left side ofFig. 2; but said pin may be laced in inoperative position, as shown at te right side of said Fig. 2.

It will also-be seen that the drum may be rotated so as to bring theshaft Q at what may be termed the bottom of the drum,

so as to be most convenient of access for operating the racks Jregardless of the large size of the drum, the sections D E then being atthe top of the drum, as shown in Fig. 2.

When the racks are operated in reverse direction, the section D isadvanced outwardly, moving with it the section E, the two sections thenbeing returned to their normal position, restoring the continuity of thedrum, after which the sections are locked from inward movement. For thispurpose I employ the rod or bolt W, whose end portions are adapted toenter eyes or sleeves X as its bearings, which depend from the shaft L,on which the pinions K are mounted, said rod having connected with itintermediate of said bearings the lever Y, which is mounted on a fixedmember and held in operative position by the spring Z, which is suitablyapplied to said rod and its sleeves.

The rod W has connected with it a casting or head W, on which is thebolt W the lat ter being adapted to enter an opening in the adjacentrack J, and thus render the rack immovable, whereby the section D isfirmly held in its normal position. 'When, however, the lever Y isproperly operated, the bolt WW is withdrawn from the rack, thusreleasing the latter, after which the shaft Q may be retated to open thesections D E, as previously described.

When the warp A is removed from the 'drum, it may be of the form of aloop, as in Fig.4, when bars A are inserted in the ends of the loop,whereby the warp may be carried to and fitted on the sleeves V, whichare supported on the pins V, after which the warp may be tied atintervals and then be removed from said pins, so as to be easily takenelsewhere without dragging or being otherwise injured.

The drum has its periphery covered by-material, such as oil-cloth, asshown at A Figs. 1, 4, and 6. This is removed with the printed warp fromthe drum, (see Fig. 4,) the oilcloth being afterward disconnected fromthe warp when the latter has been printed.

The bars A are each provided with a groove A, so that when the warp iswound around the same it may be held thereon by the action of the rod N,which presses the warp into said groove, the bar and rod being graspedby hand, as shown at the right of Fig. 4. By these means the warp isprevented from slipping, and the colors in the warp are retained inalinement.

The means for supporting the warp or yarn after it is removed from thedrum form the subject-matter of another application for patent, SerialNo. 340,763, filed October 26, 1906.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is
